Import Tips

Provide chemical analysis confirming 13CR stainless composition (min 12.5% Cr) to distinguish from carbon steel equivalents

Use ISPM-15 compliant wooden cradles for shipping; improper packaging leads to crushing damage claims

Pre-clear with CBP on 'imported with coupling' status—separate shipments risk 7304 reclassification and higher scrutiny
